In Figure 6, there is shown a modified form of the form and also for holding the sections of the form in proper spaced relation.

It should be understood that certain detail changes in construction may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claim.

ing a welded joint rigidly connecting one of the terminals of the strands together and the one of the.

sides of said Washers thereby reinforcing and I strengthening the tie intermediate the wedgereceiving loops thereof, the washers constituting metal used in forming thewelded; joint Washers.
